WIRE MATTRESS FABRIC.

Application filed April 26, 1913.

To all whom it may concern:

Be it known that 1, WILLIAM, A. HOLT, citizen of the United States, residing at Mebane, in the county of Alamance and State of North Carolina, have invented certain new and useful Improvements in Wire Mattress Fabrics, of which the following is a specification.

My invention relates to bed-bottom fabrics and more particularly relates to that class of fabrics which are made of intercon' nected bent wire units.

The primary object of my invention is to provide a fabric of this class so constructed that while it will yield readily to the weight of a body, yet a heavy person lying on one side of the mattress will not affect the other side to depress it and thus the lighter person will not be in an uncomfortable position and under a constant tendency to roll toward the heavier person.

A further object of the invention is to provide an improved bed bottom fabric wherein diagonal strains are obviated, these diagonal strains being objectionable for the reason that they act to draw in the longitudinal edges of the fabric and therefore require the longitudinal edges to be positively connected to a side rail.

A further object of the invention is the provision of very simple units which may be readily linked up with each other so as to form a fabric of the character described.

Still another object is to so construct the units from which the fabric is composed that the members which would be likely to carry or transmit the diagonal strain before referred to, are spaced from each other and not connected so that the diagonal strain is interrupted across the entire fabric, this being secured by so forming the units and so arranging them with relation to each other that the members diagonally extending in one direction alternate with members diagonally extending in another direction.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a top plan view of a mattress constructed in accordance with my invention. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a perspective view of one Specification of Letters Patent.

of the N-shaped links. Fig. 4; is a perspective view of one of the single straight links used in connecting the N-shaped links.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to the drawings, 2 designates a side rail and 3 the opposed end rails of a spring mattress frame, said rails being of any suitable construction but are preferably in the form of angle bars rigidly united at the corners by bolts and nuts. I wish it understood that I do not wish to be limited to any particular construction for this frame as it forms no part of my invention.

My improved mattress fabric is composed mainly of N-shaped unit links 4, each com prising a leg 5, a diagonally extending leg 6 and a leg 7. At the intersection of the leg 6 with the legs 5 and 7, loops 8 are formed whereby the links may be engaged with each other, and at the ends of the legs 5 and 7 vertically disposed hooks or loops 9 are formed for the same purpose. I also use straight links 10 illustrated in Fig. 4. It will be seen from Fig. 1 that I arrange these N-shaped links 4 in transversely extending rows or series and that the links of each row are reversely disposed to the links of the next adjacent rows. It is, of course, necessary that the eyes or loops 8 of one row shall come opposite to and join with the hooks or loops 9 of the links of the next adjacent rows and therefore it is necessary to dispose the N-shaped links of one row or series in staggered relation to the i\!-- shaped links of the other row or series. Thus in row A, only N-shaped links are used and these links are spaced from each other. In row B, however, the N-shaped links are reversed relative to the row A and are also placed in staggered relation so that the leg of the first N-shaped link of the row B will engage with the eye or loop 8 of the first N-shaped link of row A. It is necessary, therefore, to use intermediate links to connect the first N-shaped link of row A with the first N-shaped link of row G. This is done by using the intermediate link 10 and also connecting the loop of the first N- shaped link of row C with the loop of the first N-shaped link of row A by means of the diagonally disposed link 10 It is'also necessary to use'the straight links lO at intervals to connect the loop 8 of one N-shapedlinkwith the loop 8 of another N-shapedlink in the row or series next to the row or series adjacent to the first-named link, as illustrated in the series B at 10 While I have shown five transversely disposedseries of linked units, and three longitudinal series, it will of course be understood that I may use any desirednumber de pending upon the size of the mattress. The transverse series of links at each end of the mattress are connected to the frame by means of coil springs 11 which engage With the loops 8 and hooks 9 of the N-shaped links.

It is to be particularly pointed out that the' diagonally disposed members 6 break joints with each other as it were, that is, there is no line of diagonal members extending continuously across the mattress fabric, but that the alternate'diagonal members', whether these are the diagonally arranged bars 6' or the diagonally arranged links 10*, extend practically at right angles to-each other. By this arrangement 1 provide a mattress fabric including a plurality of diagonally disposed linking members arranged in a plurality of transverse series, these linking members being either the links IO 'or the membersb ofthe N-shaped links, the diagonal linking members of one series beingdisposed at an angle to the diagonal linking members of the next acent' series. It'is by this construction that I avoid the diagonal strainsbefore referred to which tend to cause the contraction ofthemiddle portion of the mattress fabric When weight is disposed upon the mattress.

A- mattress fabric constructed in" accordan'cewith my invention has ample'resiliency, but it permits'a portion of the mattress to yield withoutmore than slightly affecting the remainder'of the mattress, and itfis possible' for one-half of the fabric to be very greatly depressed as by the weight of a heavy person while the remainder of the fabric remains practically normal or is depressed slightly by the weight of a light person. There is no tendency therefore for th'emattress to be inclined from one edge downward to the lowest point of the mattress fabrie as is usual in wire mattresses, and therefore there is no tendency for the lighter person to roll' toward the heavier person.

The fabric as above described is very simple, the links are easy to make and easy to assemble; and the mattress is strong and durable.

What I claim is: v j

1. A mattress fabric including N-shaped units having two parallel legs and a diagonal leg joining the parallel legs, the units being arranged in a plurality of series, thediagonal legs of one series of units being disposed at a-n'angle to the diagonal legsof the next adjacent series of units.
